They are fast and strong, capable of bringing down a large deer and can be a dangerous threat to humans if proper behavior is not exercised when in their presence. Check with park rangers to learn proper behavior while in the park.

Mule Deer. The mule deer, also known as the black-tailed deer, can be distinguished from other deer by its large ears. It is the mountain lion's favorite meal. They feed mainly on shrubs, leafy plants, and grass.

Coyotes. Coyotes are a small species of wild dog of reddish, brownish, or even black color that are often mistaken for wolves. Because they do their hunting for small rodents at night, dawn or dusk, humans rarely see them.

Cottontail Rabbit. The desert cottontail rabbit is a brownish color lined with black above and white below. Their ears are relatively long, and they are quick runners. Cottontails eat grasses and green plants during the spring and summer and bark and twigs during the fall and winter months.
